BmcK-cUr-orr TABLE.

The 4present invention relates to brick cut of tables wherein peculiarshaped brick are cut by a wire or arseries of wires passing transverselythrough a column ofy clay, theV column of clay resting and moving upon aplaten or support, abovewhich column of clay is located an upper or topplaten ar ranged parallel withthe clayy column supporting platen, i

The objectsl of the present invention are, first, to provide means forguiding the brick cutting wire or wires and second,to so guide the wireor wires that the column of clay will be cut into "blocks of the desiredsize, the faces of which are provided with what might be termed oppositeconcaved' andconvexed faces, the convexity and concavity of the facesbeingdivided about midway between the longitudinal centers of the brickor blocks. l attainthese objects together with other objects readilyapparent to those skilled in the art by the construction and arrangementof the various devices illustrated in the accompanying drawingsy inwhichl Figure 1 is a side elevation of the cut off table showing thecolumn formingv die. Fig. 2 is atop plan view of the same# Fig. 3 is atransverse vertical section on line 3 3, Fig. 2. Fig. 4c is alongitudinal vertical section showing the position of the cutting iwires at their positions midway between the ends of the brick orsubstantially so. Fig. 5 is a similar view showing the position of thewires at the beginning of the cut or at the end of the cut. Fig. 6 is aplan view showing a portion of the top platen illustrating the slots inthe lower platen in dotted lines. Fig. 7 is a top plan view of a portionof the bottom or clay supporting platen. Fig. 8 is a perspective view ofa cut brick or block produced.

Similar numerals of reference indicate corresponding parts in all theligures of the drawing.

In the accompanying drawings, 1 represents the die which is connectedtor an ordinary brick machine which machine within itself 'forms nospecific part of the present Specification of Letters Patent.

invention. The top platen 2 and the bot-` tom platen 3 are connected tothe thrust bars 4 yby means of the flanges V5 and the clamping bolts 6or their equivalents, the only object and purpose beingto space theplatens 2 and 3 so that the column of clay will pass between the twoplatens, said platens being so arranged with reference to each otherthat the upper platen will be spaced ashort distance from the top of thecolumn ofy clay, this being preferablevas by sofspacing the platensthere will be no frictional contact as between the upper face of thecolumn of clay and the bottom or undery thrust bars are connected tothemovable frame 7, which frame within itself may be Y of the ordinaryconstruction and is mounted upon suitable traveling rollers or wheels 8,which travel back and forth upon suitable tracks or ways 9. It will beunderstood that the frame 7 together with the different parts carried bysaid frame must necessarily travel in unison with the travel of the claycolumn adjusting ythe* die of the brick machine during the time thecutting wires are passing'through the column of clay and in order toaccomplish this simultaneous movement of the frame carrying the cuttingwires and the `columnrof vclay the usual mechanism for intermittentlyand automatically moving the frame with the column of clay must beprovided but such mechanism is well 1 known in the art and has nospecific reference yto my present invention and for that reason suchmechanism is not illustrated but it will be understood that in order tocarry out the complete working of a brick cutting machine such mechanismmustvnecessarily be present.

The top platen 2 and the bottom platen 3 are provided with the curvedslots 10 and 11, which slots are formed of suiiicient length to allowthe cutting wires to move back and forth suliicient distance to passthrough the column 0f clay. For the purpose of producing a brick orblock such as shown in Fig. 8 the curved slots 10 and 1l are arranged asshown in full lines and in side of the top platen 2. These platens 2 f eand 3 are carried by the thrust bars 4, which dotted lines Fig. 6; thatis to say the slots in l 10 and 11, the cutting wire or wires will fol`low the curvatureV of the slots and by reason of the fact that the slotsin the 'lower platen are Ycurved in the opposite direction from theslots in the upper platen the wireor wires will change position duringthe movement.

of the wire` or wires, the movement being such as to give to the facesof the' brick, thel curvature illustrated in Fig. 8. In Fig. 4E thewires are shown in their positionsassumed about midway between theeXtreme movements ofthe Wires and in 5 the wires are shown in theirpositions assumed at the beginning of the cut or at the formation of acut. By providing curved 'slots' in' the top and bottom platens andspacing, said platens from each other a sufficient distance to allow acolumn of clay to pass between said platens, the wire or wires will in asense be oscillated, that is to say` the lower portions of the wire willbe moved through the arc of a circle and the upper portion of the wirewill be moved in a similar arc but of opposite curvature, therebyproducing a bars 13 being provided with the usual con-V necting heads14, whichfare provided with the springs 15, but these parts are'commonin brick cut off tables and need no specific description as the onlyobject is to hold the wires in proper tension andrso far as the .Copiesof this patent may be obtained for present invention'is concerned may beof any wellknown mechanical construction.

does not take place but they cross each other in different horizontalplanes so that the ends of the slots are located in di'erent verticalplanes, by which arrangement the cutting wire or wires are not in a truevertical position at vany time, except when the wires are at thek pointswhere the slots cross each other in dierent horizontal planes.Y

Having fully described my invention what I claim as new and desire to,secure byLetters Patent, is-

In a brick cut off table, a cut 01T frame, a lower platen adapted tosupport a column of clay, said platen provided with. a series oftransverse curved slots, an upper platen located above said column ofclay, said upper platen provided with a series of transverse, oppositelycurved slots, a bar adapted to reciprocate transversely above thev claycolumn, a second bar adapted to reciprocate transversely beneath theclay column, and wires carried between said bars, said wires locatedthrough the oppositely curved slots in the upper and lower platens.

In testimonyY that I claim the above, I have hereunto subscribedl myname'k in the presence of two witnesses.
